PHP - Session destroy after closing browser

Question

Though this question has multiple duplicates i could not find proper solution for me. Need Some help.

I have used ini_set(\'session.cookie_lifetime\', 0);

Answer 1

Use a keep alive.

On login:

session_start();
$_SESSION['last_action'] = time();

An ajax call every few (eg 20) seconds:

windows.setInterval(keepAliveCall, 20000);

Server side keepalive.php:

session_start();
$_SESSION['last_action'] = time();

On every other action:

session_start();
if ($_SESSION['last_action'] < time() - 30 /* be a little tolerant here */) {
  // destroy the session and quit
}
